@hmp68239 Could you please share output for the command: env | grep -i proxy

[nehaljwani]

I could reproduce this like this:
In one tab, type:

ssh -D 9889 localhost

In some other tab:

export all_proxy=socks5://localhost:9889 # Could have used ALL_PROXY too

Download and install latest conda for python 3:

./Miniconda3-latest-Linux-x86_64.sh -b -p /tmp/scratchconda

Activate and run conda install python:

source /tmp/scratchconda/bin/activate
conda install python
...
...

Fix: Install requests with socks support. (a.k.a PySocks?) Interestingly, this doesn't require access to internet, since it is already present, but not setup.

pip install -U requests[socks]

Now conda is happy.

[kalefranz]

Yes, if you have configuration on your system that requests is recognizing for a socks proxy, you'll need to pip install -U pysocks. I don't think the default repo currently have a conda package for pysocks. Note the conda-forge pysocks version is one that's specifically noted to be not compatible with requests.
